title: Small leiomyosarcoma of the renal capsule: CT findings.
abstract: Three unusual cases of small-size leiomyosarcoma of the perirenal space were studied with CT. The renal capsule has been proved to be the origin of this type of tumor. A CT examination is accurate in suggesting the site of origin and excluding a renal cell carcinoma. However, unless evidence of invasion is noted, it is impossible on CT features to discriminate leiomyosarcoma from a benign leiomyoma.
